Simple swift array append not working

Question

I know this is going to be super elementary, but I have this piece of code:

var labels: [String]?

func initVC(image: Images){
    self.image = image

    le         


        

Answer 1

You are declaring the labels variable but never allowing it to store information. This means that it does not necessarily exist, since it is not initialized, and therefore cannot be used.

For it to be useable, you must initialize it

var labels:[String] = []
